FIELD

One embodiment relates to battery packs and/or holsters and, more particular, to an external battery pack and/or holster for mobile electronic devices.

BACKGROUND

Many mobile devices (e.g., mobile phones, digital assistants, mobile communication devices, handheld computing devices, personal music/video/content players and storage devices) are often powered by battery power sources. Such battery power sources are often housed within the mobile device and may be changed and/or recharged as needed. However, as inure powerful mobile devices are designed, these tend to consume power more quickly, thereby shortening the time between charges. This tends to limit the usefulness of the mobile device since the user must find a power source to recharge the battery source and wait until it is recharged.

Additionally, after a certain number of recharges, a battery source may need to be replaced as it may no longer hold a charge. Oftentimes, it is not easy to replace a battery source as the mobile device may need to be disassembled or opened to reach the battery source.

Therefore, a way is needed to extend the time between charges of mobile devices and/or continue to power the mobile device even after an internal power source has been depleted.

SUMMARY

According to one embodiment, a battery pack for a mobile communication device is provided comprising a casing and one or more rechargeable power cells. The casing may define a cavity that conforms, at least partially, to the outer shape of the mobile communication device. Additionally, the casing may further define one or more access openings to permit access to integrated interfaces (e.g., power button, camera lens, audio jack, etc.) of the mobile communication device.

The one or more rechargeable power cells may be housed within the thickness of the casing. For example, the power cells may be housed within the thickness of a back plane of the casing. The casing may secure the mobile communication device within the cavity while at least one surface of the mobile communication device remains exposed.

The battery pack may also include an internal interface and/or external interface. The internal interface may engage a corresponding interface on the mobile communication device to provide power from the one or more rechargeable cells to the mobile communication device.

Now that such applications may, in some instances, continue to operate even if the mobile device is detached from the battery pack.

According to yet another feature, the battery pack may include and inductive recharging device or a near-distance recharging device so that its power cells may be recharged without actually physically plugging it to a recharge power source.

First Embodiment of Battery Pack

FIG. 1 illustrates a perspective view of a battery pack for a mobile device according to one example. In this example, the battery pack 100 is shaped to receive or house a mobile phone within a contoured cavity 102. The battery pack 100 has an integrated rechargeable power cell capable of providing power to operate and/or recharge a mobile device (e.g., iPhone™ by Apple Inc., etc.).

FIG. 2 illustrates how a mobile device can be housed within the battery pack 100 of FIG. 1. As can be appreciated from this figure, the battery pack 100 is shaped to closely wrap around the mobile device 202 and serves as a protective case for the mobile device 100.

FIG. 3 illustrates a front view of the battery pack 100 of FIG. 1. The battery pack 100 includes a back plane 304, first and second sides 306 and 308, a bottom side 312, and a top side 314. The back plane 304, first and second sides 306, bottom side 312 and top side 314 may be shaped to form a pocket or cavity 102 in which a mobile device to be powered can be housed. The top side 314 of the battery pack 100 may slide out to allow insertion and removal of the mobile device.

Referring again to FIG. 1, the battery pack 100 may include one or more openings 104, 108, 110, and 112 to facilitate access to various features of the mobile phone. For instance, a first opening 104 on the back plane 304 of the battery pack 100 may allow unobstructed view for a camera lens on the back of the mobile device. A second Opening 108 may provide access to a screen on/off switch for the mobile device. A third opening 110 may provide access to an audio jack on the mobile device. A fourth opening 112 on the first side 306 may provide access to a volume control sliding switch.

The battery pack 100 may also include a connector or interface 106 within the cavity 102 (e.g., on the bottom side 312) through which power can be provided to the mobile device from the internal power cell of the battery pack 100. Additionally, the connector 106 may be coupled to an external interface to provide input and/or output signals to the mobile device.

From FIG. 1, it can be appreciated that the battery pack may include two sections that separate to allow insertion of the mobile device and can then be coupled together to secure the mobile device in place. The size and shape of the battery pack 100 may be approximately that of the external contour of a mobile device to which it is intended to provide power.

FIG. 4 illustrates the battery pack of FIG. 1 in an open configuration. The battery pack 100 may include a bottom section 402 and a top section 404 that can be separated from each other to insert a mobile device within the battery pack 100 and can then be coupled together secure the mobile device in place. For example, the bottom section 402 may include receiving grooves 406 a and 406 b that receive rails 408 a and 408 b from the top section 404. In this manner, the top section 404 can be coupled to the bottom section 402 by pressure fit. For example, a tongue section 802 (FIG. 8) may slide on to the top section 404 such that an engaging tab 412 couples into a receiving groove 804 (FIG. 8) to secure the top section 404 to the bottom section 402.

FIG. 5 illustrates a top view of the battery pack 100 of FIG. 1. In this view, the top side 314 of the battery pack 100 is shown and the first opening 104, second opening 108, and third opening 110 can be appreciated.

FIG. 6 illustrates a bottom view of the battery pack 100 of FIG. 1. In this view, the bottom side 312 of the battery pack 100 is shown. In this view, an external interface 602 (e.g., micro USB connector) is shown. This external interface 602 may serve to recharge the internal power cell of the battery pack. Additionally, the external interface 602 may also provide a pass-through signaling interface for the internal connector or interface 106, thereby allowing the mobile device to communicate via the external interface 602. A switch 604 may also be located on the bottom side 312 of the battery pack and can function to switch power from the battery pack On or Off. That is, when the mobile device has sufficient power on its own, the power cell of the battery pack is not needed and can be switched Off until it is needed.

FIG. 7 illustrates a back view of the battery pack 100 of FIG. 1. In this example, a test button 702 is provided that, when pushed, causes plurality of LED lights 704 to indicate the power or charge level of the internal power cell of the battery pack 100.

FIG. 8 illustrates back view of the battery pack 100 of FIG. 1 in an open position.

FIG. 11 illustrates a second side view of the battery pack of FIG. 1.

FIG. 12 illustrates the second side view of the battery pack of FIG. 1 in an open position.

FIG. 13 is an exploded view of components of the battery pack of FIG. 1. In this example, the battery pack may include a first bottom section 1302 and a second bottom section 1304 which form a top and bottom shell in between which one or more circuit boards 1308, 1310, and/or 1312 and/or one or more power cells 1306 are housed. That is, the circuits hoards 1308, 1310, 1312 and/or power cell(s) 1306 are sandwiched between the top and bottom sections 1302 and 1304 of the battery pack 100. Consequently, the rechargeable power cell(s) 1306 may be housed within the thickness of the back plane of the battery pack.

In some instance, the circuit boards and or power cell of the battery pack may cause interference with the antenna or signaling of the mobile device which is in close proximity. Consequently, one aspect provides for reducing the size of a primary circuit hoard 1308 by adding secondary circuit boards 1310 and 1312 which are electrically coupled to the primary circuit hoard 1308. This allows reducing the size of the circuit board 1308 thereby reducing interference to the antenna of the mobile device. Additionally, the ground for the power cell 1306 may be coupled to the ground for the mobile device (via the internal interface 106) to reduce interference to the mobile device.

FIG. 14 illustrates a block diagram for the battery pack 100 of FIG. 1. The battery pack 1402 may include a power cell 1404, an internal interface 1406, an external interface 1408, and charge level indicator 1410. The internal interface 1406 may be adapted to provide a mobile device power from the power cell 1404 as well as passing signal to/from the mobile device to the external interface 1408. The external interface 1408 may allow recharging of the power cell 1404 as well as passing signals to/from the mobile device via the internal interlace 1406. A switch 1412 may allow switching power from the power cell 1404 to the mobile device On and Off as desired. Also, a charge level indicator 1410 permits displaying of the charge level of the power cell 1404. Additionally, a recharging module 1412 serves to recharge to power cell 1404 when needed.

Second Embodiment of Battery Pack

FIGS. 15-16 and 18-22 illustrate yet another embodiment of the power pack. In this embodiment, the power pack may operate as previously disclosed but does not include a top section. By removing the top section, the battery pack is more compact in size and ergonomic so that it does not significantly increase or change the size, thickness, and/or shape of mobile communication device 1602 secured thereto.

FIG. 15 illustrates a perspective view of the battery pack 1502.

FIG. 16 illustrates a perspective view of the battery pack 1502 with a mobile device 1602 inserted therein.

FIG. 19 illustrates a front view of the battery pack 1502.

FIG. 20 illustrates a front view of the battery pack 1502 with the mobile device inserted therein.

FIG. 21 illustrates a back view of the battery pack 1502 with the mobile device 1602 inserted therein.

FIG. 22 illustrates a side view of the battery pack 1502 with and without the mobile device 1602. Note that, in some embodiments, the left and right sides may be symmetrical.

Extendible Processing and Interfacing Platform

FIG. 17 illustrates a battery pack that also operates as an extendible processing and/or interfacing platform for a mobile device. In one example, the battery pack 1702 may operate as described with reference to FIG. 14. In addition, the battery pack may also include one or more processors 1706 and/or one or more interfaces 1708. The one or more processors 1706 a and 1706 b may allow a mobile device coupled to the internal interface 1406 to extend its processing capabilities. For instance, the mobile device may cause one or more applications to be executed on the one or more processors 1706 while using a user display on the mobile device as an output interface. Additionally, the processors 1706 a and/or 1706 b may be purpose-specific processors that allow the mobile device to perform particular tasks not otherwise possible on its own. For example, the processors 1706 may provide analog-to-digital conversion, audio signal sampling, temperature measuring, etc., which may not be available to the standard mobile device.

The one or more interfaces 1708 a and 1708 b may also provide the mobile device a means by which to communicate or acquire signals. These interfaces 1708 may effectively expand the communication interfaces available to the mobile device by providing wired and/or wireless communication interfaces for various types of signals (e.g., audio, infrared, etc.).

The battery pack 1702 may also include a recharging module 1704 that facilitates recharging of the power cell 1404. For example, the recharging module 1704 may be a wireless or cordless charging device that inductively or otherwise facilitates recharging of the power cell 1404.

In one example implementation, the battery pack 1702 may be adapted to function as a Medical Processing Unit which may have build-in capabilities for monitoring real-time health conditions (e.g., alcohol levels in breath, pulse, temperature, blood pressure, test and/or diagnose diabetes, etc.) via build-in test port. Consequently, the battery pack 1702 can collect and/or process such collected data and store it in the mobile device. Note that the processing of such data may be directed by an application that operates either on the one or more processors of the battery pack 1702 and/or the processor(s) of the mobile device. According to one feature, if an abnormal health condition occurs (e.g., a heart attack, fainting, seizure, etc.), the Medical Processing Unit may detect this condition and automatically activate the mobile device (e.g., cellular phone) to send urgent text message or entails to a doctor, hospital, or emergency responder. The responding party (doctor, hospital, emergency responder) may be able to locate the patient via a global positioning system or information from the mobile device.

In another example implementation, the battery pack 1702 may be adapted to function as a Gaming Processing Unit that may include the capability of turning the mobile device into a real handheld gaming device with joysticks or large PSP/DS type of gaming buttons and communication devices. Consequently, the mobile device may be configured to operate as an input and/or output interface (e.g., via a display on the mobile device or battery pack) for a game.

In yet another example, the battery pack 1702 may be adapted to function as a Home Entertainment Unit that may include the capability of turning the mobile device into a Universal Smart Remote Control which can control all the IR activated units in a home or office (e.g. control garage doors, television sets, security alarm, air conditioning, lighting, etc.). For this purpose, the battery pack 1702 may include various interfaces 1708 that provide the specific infrared and/or wireless protocols and/or signaling to control such devices.

Speakers & Microphone

Another feature may provide for one or more speakers to be included as part of the battery packs or holster (illustrated in FIGS. 1-22). For instance a low-profile speaker may be housed within the back plane of a battery pack so that the sound may be emitted from the rear or sides of the battery pack. When a mobile device is inserted and coupled to the battery pack, it couples to an interface that electrically connects the speaker to the mobile device. The mobile device may send audio or sound signals to the speaker via an interface with the battery pack. This allows a user to listen to audio stored in the mobile device without the need, for headphones.

Similarly, another feature may provide for one or more microphones to be included as part of the battery packs (illustrated in FIGS. 1-22). One or more microphones may be housed within the battery pack (e.g., back plane) so that they may capture sound from a user. The microphone may be electrically coupled to an interface that allows sending captured audio signals to a mobile device that may be coupled to the battery pack.

According to yet another feature, when the mobile device is coupled to the battery pack 1702, it may cause one or more applications to execute on the processors 1706. These applications may continue to operate or execute even if the mobile device is removed or decoupled from the battery pack 1702. For example, the battery pack may continue to collect data (e.g., monitor medical conditions for a patient to which it is coupled) and wirelessly transmits the collected data or an alarm to the mobile device. This is possible since the processors 1706 may be powered by the power cell 1404 and can be configured to operate whether or not the mobile device is coupled to the battery pack.

Integrated Display

In some embodiments of the battery pack 1702, battery pack 1702 may also include an integrated display or screen. For example, the integrated display may be on the outer surface of the back plane of the battery pack. Alternatively, the display 1710 may slide out from within the housing of the battery pack. This integrated display 1720 may allow displaying additional information or data to a user. The additional display screen may be electrically coupled to the mobile device (via an interface) to allow the mobile device to send images or video to the additional display screen.

In another example, the rear of the back plane may house a Braille input and/or output interface that electrically coupled a mobile device mounted within the holster or battery pack.

In yet another embodiment, the rear of the back plane may provide a keypad that serves as an input to the mobile device.

According to another feature, the battery pack and/or holster may provide an external interface (e.g., Bluetooth wireless interface, USB port, infrared port, etc.) that may allow the mobile device mounted in the battery pack and/or holster to communicate via that external interface. Thus the external interface may provide a different wireless interface than provided or supported by the internal system of the mobile device.

Consequently, a battery pack for a mobile communication device is provided comprising: (a) a casing or holster (e.g., FIG. 4, 402 and/or 404) defining a cavity (FIG. 1, 102) that conforms, at least partially, to the outer shape of the mobile communication device (FIG. 2, 202); and/or (h) one or more rechargeable power cells (FIG. 13, 1306) housed within the thickness (between 1302 and 1304) of the casing. The casing secures the mobile communication device (202) within the cavity (102) while at least one surface (e.g., a display screen) of the mobile communication device remains exposed. An internal interface (106) engages a corresponding interface on the mobile communication device to provide power from the one or more rechargeable cells (1306) to the mobile communication device. An external interface (FIGG. 6, 602) electrically couples to the internal interface (106) to transmit signals from the mobile communication device to an external device. The external interface (602) may further serve to recharge the one or more rechargeable power cells. The casing further defines one or more access openings (104, 108, 110, 112) to permit access to integrated interfaces of the mobile communication device (202).

The battery pack (100 or 1502) may further include a recharging device (1704) integrated within the battery pack that wirelessly recharges the one or more rechargeable power cells (1306).

An extendible communication and/or processing platform may be provided to mobile communication device by the battery back. For instance, a plurality of communication interfaces (1708) may be coupled to the internal interface (106 or 1406), wherein the mobile communication device (202) can transmit and receive signals via the communication interfaces (1708). Similarly, at least one processor (1706) may be coupled to the internal interface (106 or 1406), and adapted to collect information via one or more interfaces (1708) of the battery pack and provide the collected information to the mobile communication device (202). At least one processor (1706) may be adapted to execute one or more instructions under the control of the mobile communication device (202). According to one feature, a display interface (1710) may be integrated into the battery pack to display information to a user.

The thickness of the battery pack (100 or 1502) is less than twice the thickness of the mobile communication device. In some embodiments, the thickness of the battery pack may extend, for example, between ten and ninety percent more than the thickness of the mobile communication device. For example, the battery pack may extend a mere thirty to fifty percent more than the thickness of the mobile communication device.

Similarly, a battery pack (100) for a mobile device (202) may include (a) a back plane (304), (h) a first and second sides (306 and 308). (c) a bottom side (312), wherein the back plane (304) and first (306), second (308) and bottom (312) sides define a cavity (102) for mounting the mobile device (202); and (d) one or more battery cells (1306) housed within the thickness of the back plane (304). One or more speakers may be housed within the thickness of the back plane (304) and electrically coupled to an interface (106) to allow a mobile device (202) mounted in the cavity (102) to send audio signals through the one or more speakers. Similarly, one or more microphones may be housed within the thickness of the back plane (304) and electrically coupled to an interface (106) to allow a mobile device (202) mounted in the cavity (102) to receive audio signals from the one or more microphones.
